What is denoted by the presence of high inputs in logic circuits?

The presence of high inputs in logic circuits indicates an Active State. In digital logic, a high input typically represents a logical '1', which corresponds to the circuit being in an active condition or executing a function. When a circuit is in the active state, it can drive outputs, perform computations, or respond to other inputs according to its design.

A high input effectively enables the associated logic gates or components to perform their intended operations. This is fundamental to digital design, as outputs can vary based on the combination of high and low inputs (logical '0'). In essence, the active state is critical for the functioning of circuits because it is when the desired logical operations occur, allowing various circuit configurations to lead to particular outcomes.
